HappyBirthday!

We love to hear about why and how you Wonder, and we’re excited to celebrate our fifth birthday with all of our Wonder Friends. We can’t think of a better way to get things started than by revisiting this song that was written by Wonder Lead Ambassador Jon Fines and performed by his kindergarten class!

Join the Party!

Birthday Mystery Game

How do these clues add up to a special birthday surprise? Check back throughout the day for more hints. A new image will be added to the gallery every hour on the :05. Post your guesses on Twitter or Facebook using the #CelebrateWonder hashtag.

So, have you guessed how the clues above are part of Wonderopolis’ birthday? Sure, the birthday cake makes sense, but how do the water, clocks, gum, shovels, and french fries fit in?

Each picture represents one of the 25 most popular Wonders of the Day® on Wonderopolis, and we’re celebrating our birthday by releasing a brand new e-book Have You Ever Wondered? The Top 25 Wonders of the Day® Explained.

The digital book is available for purchase here, or you can download it for FREE by making a donation of $5 or more to Wonderopolis. There are additional reward packages offered for different levels of giving, and any donation of $5 or more will receive a free download of the new e-book.

We hope you’ve had as much fun as we’ve had over the last five years sharing Wonder together. We're excited to see what Wonders are next!
